Refer to the exhibit.
Which trunks would be most suitable for Connection Y?
A.
an H.225 trunk (gatekeeper-controlled)
B.
intercluster trunk (gatekeeper-controlled)
C.
a SIP trunk on the U.S. cluster and an intercluster trunk on the remote cluster
D.
intercluster trunk (nongatekeeper-controlled)
E.
No extra connections are required. As long as IP connectivity exists, you need only configure a
route pattern for each site. The Cisco Unified Communications Manager will automatically forward
the calls over the WAN if the destination directory number is not registered locally.
Since the communication is only between two CUCM (assuming they are not part of the same cluster) the ideal connection would be intercluster trunk (nongatekeeper-controlled). Option D.
